Why do the brakes on my lexus is220 keep siezing?

Connect it up to a High Level Scan Tool and read the codes and live data. May be a bad connection on the ABS sensor or the brake wear sensor depending on the model.

Hey Willie,
Brakes are what keeps you from destroying OTHER PEOPLE'S vehicle... Take this to a QUALIFIED expert... and get it fixed before you are forced to...

sounds like the rear brake may be siezed , park on a hill let of the parking brake and see if the vehicle will start rolling , if not get the brakes overhauled

if i have read your problem correctly,its your fronts siezing after standing.have you tried putting your foot on the brake when driving to derust the rotors and centralise the pads?????

The bleeder screw is in the back next to the brake line into the caliper. Start the bleeding at the right rear, farthest from the reservoir. Then move towards the front left. Keep checking the fluid level and make sure you don't let go of the pedal with the screw loose. Get a 6 point box wrench on there , about 8mm, and a piece of hose to run the fluid into an empty can. Check it out, hope this helps.

the first thing to do is to slacken the handbrake adjuster on the lever off completely.then if you have rear drum brakes remove the drums and make sure that the handbrake levers on the shoes are not siezed and are returning to the stops plus that the auto adjusters are not siezed if not free them off so they are using wd40 or whatever and the linings/drums are ok then reasemble and pump the brake pedal a few times to let the auto adjusters work then readjust the lever to about 5 to 7 clicks if you have got rear discs then one off the rear calipers may have siezed or both handbrake cables should also be checked for being siezed

Call your local brake shop, prices on parts and labor differ in various parts of the country

make sure engine is only warm to the touch, using a 22mm wrench or o2 sensor socket remove A/F sensor. These are known to sieze in manifold

check your fluids and bleed the brake system , if that is all the issues your having . if low on fluid and keeps draining out then you have whats known as a caliper seal broken and that means $30-50 bucks for a new one/rebuilt , i know i drove mine like that for a bit and had to replace the driver side.
